FISH-PLATE CHAIR FOR RAILWAY-RAILS.

Specification of Letters Patent.`

Application filed November 11, 1909.

Patented Aug. 1e, 1910. Serial No. 527,419.

To allwtom it may concern: i

Be 1t known that I, F RANoIs WV. POOL, a

Y subject of the` King of Great Britain, and

a resident of I-Iavre, in the county of Chouw teau and State of Montana,have invented a new and Improved F ish-Plate Chair for RailwayRails, ofwhich the following is a full, clear, and exact description.

Among the principal objects which the present invention has in view are:to provide a joint for railway rails embodying fish-plates and chairsfor uniting and supporting the ends of the said rails; to provide astructure of the character above mentioned having means exclusive of thefish-` plate bolts upholding t-he fish-plates in rigid relation to therailway rails; andto provide a construction for" a device of thecharacter speciiied which results in a maximum economy in weight andstructural strength.

One embodiment ofthe present invention is disclosed in the structureillustrated in the accompanying drawings, in which like characters ofreference denote corresponding parts in all the views, and in whichFigure 1 is a perspective view of two fragmentary ends of railway railsjoined and supported by fish-plate chairs constructed in conformity withthe present in vention; Fig. 2 is a cross section of a rail showing inside elevation the joined fishplate chairs in operative position; Fig. 3is a perspective view of one of the said fishplate chairs separated; andFig. t is a plan view of the fish-plate chairs showing the railwayrails, the tread of the same being removed.

In a former patent granted to me the 19th day of April, 1904, No.758,018, for improvements in railway chairs, was set forth and claimed astructure similar in many respects to the present invention. Thesimilarity broadly consists in the employ ment of two base plate members5, 5, in the ends of which are formed perforations 6, 6 suitable for thepassage of fastening bolt-s. Carried upon each of the members is avertical projection 7, 7, the face of which is removed from and inclinedtoward the railway rail to receive the inclined surface of a head orbracket extension 8, 8. In the present instance the heads 8, 8 in eachof the members are provided with a fish plate 9, 9. The fish-plates 9, 9are extended at suitable distances to either side of the heads 8, 8, andare provided with one or more bolt holes 10, l0 to aline with bolt holesprovided in the end sections of the rails A, A. The faces of theiishplates 9, 9 are shaped to the size of the web of the rails A, A,conforming to thefjunction curves or inclines of the web with the flangeand tread of the said rail, as isusual with iish-plates of the presentknown construction.

The bodies of the heads 8, 8 and the projections 7, 7 are formed vinhollow construe tion, the castings, if castings be used, being properlycored to produce the lightest practicable structural weight with themaxi-- mum structural strength. With the same idea in view, that is, toreduce the weight of the structure, I have provided the bed platesthereof with a series of parallel grooves 11, 11, the vertical wallswhereof are underneath and have full capacity for carrying the weightreceived upon the chair.

Vith a structure thus formed the operation of: assembling the same inoperative position is as follows: The separate mem- 1 bers arepassedunder the rails A, A to be joined, the fish-plates 9, 9 being separatedsufliciently to permit the rails to slide readily between the same. Therails A, A having been set in desired posit-ion, the fishplate chairsare then drawn together, the inclined faces of the heads 8, 8 and theprojections 7, 7 abutting, and each sliding upon the other. The resultof the sliding action is to wedge each of the heads 8, and theiishplates 9 carried thereby, against the butted ends of the rails A, A.In this position the projections provided in the rails to receive bolts12, 12 will aline with the bolt holes 10, 10 formed in the sh-plates 9,9. In this `position the bolts 12, 12 are extended through theperforations, and nuts 13, 13 are thereon fastened and set up. Thechairs are usually assembled to ride on the same tie. This having beenprovided, the usual spikes 14 are driven into the ties throuOh theperforations 6, 6 provided in the chairs for that purpose. With thedriving of the spikes 14 the operation of assembling and fastening inposition the` various parts con* nected with the railway joint whenformed by using the present invented fishplate chair, is completed.

The two fish-plate chair members are often provided by me with the bolts15, 15, which pass through the castings in such manner as to be drawntogether by setting up the screw nuts 16, 16.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is:

l. A fish-plate chair for railway rails comprising a plurality of baseplates each adapted to extend under and at both sides of the joinedrails; a plurality of {ish-plates having a vertical face shaped to thechannel formed by the web, tread and flange of the joined rail, saidfish-plates being laterally extended from said base plates to reinforcethe joined rails; supporting heads for said fish-plates integrallyformed therewith and with the said 'base plates, having inclined wedgingsurfaces at the rearward extension thereof, and having a separated upperand lower wall extension in the lines of thrust of said rails; aplurality of inclined surfaces having vertical planes formed in the rearof each of said fish-plates; a plurality of vertical projections formedon the said base plates and having inclined vertical planes adapted toengage the said inclined surfaces in the rear of said fish-plates; boltholes formed in said fish-plates to aline with bolt holes in the joinedrails; ,fastening bolts extendedthrough said fish-plates and said rails;and fastening devices for retaining the said members of the {ish-platechair in fixed. relation with the railway structure.

2. A. fish-plate chair for railway rails com? prising a plurality offish-plates shaped to conform to the channel of the railway rails andhaving bolt holes for securement to said rails; a plurality of baseplates each connected with one of said fish-plates disposed at the sideof the median line of said fishplates and extended under the said railin position to support the same; supporting heads for said fish-platesintegrally formed with said fish-plates and said base plates,

said supporting heads extended laterally from said base plates to reston both sides of said median line of the said fish-plates to form asupport for said {ish-plates on opposite sides of the rail meeting, therear of said supporting heads having an angular extension from said baseplates; projections formed integrally on each of said base plates andextended upward therefrom hav ing an angular surface adapted to engagethe angular surface of the supporting heads of the adjacent fish-plateto force the said fish-plates against the said rail by the wedgingaction of the angular surfaces of said heads and said projections; andmeans for securing said projections in engaged relation with said heads.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
